调研方向

使用 package.json、src/simple-form.tsx 和 src/App.tsx 中所列的文件运行 StackBlitz 复现。比较 TanStack Form 1.26.0 与 1.27.7,跟踪 onMount 的 meta 更新以及 firstName 的渲染行为。完成的标准是 firstName 初始时隐藏,并且在不触碰 firstName 的情况下更改 color 时能够正确更新。

Describe the bug

I am using custom field meta's heavily, for example style={{ display: field.state.meta?.hidden ? 'none' : 'block' }}, for every field I have set of these meta's like dataSource, hidden, disabled, and others...

in example there is two field firstName and color, I have listener.onMount that hide firstName (through field.setMeta()) if color is "red", in v1.26.0 and before it works well, after this version it does not hide until I touch the field firstName

example use v1.26.0, change package version to see the problem

Your minimal, reproducible example

https://stackblitz.com/edit/vitejs-vite-kqn6fekp?file=package.json,src%2Fsimple-form.tsx,src%2FApp.tsx&terminal=dev

Steps to reproduce
  1. notice in example field firstName is hidden by default (it is hidden in onMount)
  2. change the color to "green" field firstName will appear
  3. upgrade tanstack-form version to newer version
  4. after refresh you will notice firstName now is not hidden
  5. touch the field firstName now it will hide
Expected behavior

compare by previous steps I exp expect:

  1. notice in example field firstName is hidden by default (it is hidden in onMount)
  2. change the color to "green" field firstName will appear
  3. upgrade tanstack-form version to newer version
  4. field firstName should still hidden by default
